    Was there a relay in the Eico 730?

    I'm sure I remember one in the '730 I had -- for a while it didn't switch cleanly and put out a very gnarly buzz before it did. Sorta like a roger beep?

    But I was just checking out the schematic and the one I found had no relay. I believe it turned on the B+ when the transmitter was keyed. Details, anyone? Maybe an upgrade?
